Fabrication of materials nowadays

Fabrication is the act of forming structures or parts with the help of multiple processes of building, uniting, forging, and constructing. It is part of the overall manufacturing process. The tools used to fabricate vary just like the methods used to form the object do. However, materials used in fabrication in general in relation to manufacturing are forming metals. Other materials like thermoplastic and thermoset can also be used in combination with fabrication methods however, these methods include molding and casting. It can be employed to create components that are used in manufacturing products ranging from automobile fenders to toys. Manufacturing buildings can be done as well of course. This actually relies heavily on metal fabrication, which is shaping raw metal materials into parts and components for complete assemblies or subassemblies. Fabrication will shape a metal sheet into a custom piece. This can be done by selectively removing material from the sheet or by deforming the material into the desired form.

Not a lot of people know that 3D printing San Diego consists of many different techniques. This is also the case with sheet metal fabrication. This is essentially a broad term for multiple types of fabrication processes. Below you will find five extremely common fabrication techniques that are used to mold, cut, or shape raw metal materials into the final product.

Forming

Forming is a fabrication process used to distort or bend metal to develop components and parts. This can also be done through rolling, which is a method that utilizes CNC press brakes. Sheets of metal will be continuously fed through parallel rollers. These will shape the material into the desired shape. During the forming process, the workpiece will not lose its mass, just its form.

Stamping

Stamping creates an indentation during fabrication, so not an actual hole in the workpiece. The turret will press against the metal, which forces the die to stamp images, letters, or shapes into the metal material. This way metal sheets can be formed into specific sizes and shapes with the help of hydraulic or mechanical means. Besides that, these machines can also punch, cast, cut, and shape sheet metals to produce a ton of items.

Cutting

Cutting is an extremely common fabrication process. This technique will split or cut the material into smaller parts. Cutting is usually the first step in a way larger fabrication project, while it can also be the only step needed in the process. The modern ways of cutting makes use of machinery, which could be a CNC cutter. Methods used today include waterjet cutting, laser cutting, power scissors, and more.

Shearing

Shearing is used to remove or trim unwanted material from metal. It is done by mounting two blades beneath and above the workpiece in order to create one straight and long cut. The upper blade will force the material down, while the lower blade is fixed or stationary to fracture the metal in order to create separation. Shearing is often used to cut differently shaped and smaller lengths materials.

Welding

Another common fabrication technique is welding, which is when two or more pieces of metal will be joined together with the help of a combination of pressure and heat. The metals used can vary in size or shape. There are three main types of welding techniques: MIG Welding, TIG Welding, and Stick or Arc Welding.
